Mapping non-empty $query_string

Server NGINX
1

Hi!
I’m running a Wordpress based website on my server, I’ve set up fastcgi
cache recently. Now I want to get rid of evil-ifs, that are used to
detect
cache skipping cases, and replace them with map.

I managed to convert all common ifs except this one,

if ($query_string != “”) {
set $skip_cache 1;
}

I’m trying to replace it with non-evil map in http section.

#skip cache if query string has at least one character
map $query_string $skip_cache {
“~.+” “1”;
}

For some reason it doesn’t work as intended. It starts bypassing cache
on
ALL pages except main page.

Thanks for any help.
Alex

map $query_string $skip_cache {
“” 0;
default 1;

Already tried it, same result. Main page hits the cache, everything else

bypasses.

Are you sure your requests are processed by the right block?

Are you sure the configuration is being loaded? Since v1.9.2, you can
use
the -T command-line parameter to show loaded configuration.
On reloading configuration by sending the HUP signal, ensure there is no
error message popping up in the error logs.

If this still does not work no-one cannot help you without further
details
on the used configuration.
